Gr. Willey et al., The structure of [GaBr3(Me-3[9]aneN(3))]: The first example of a six co-ordinate gallium(III) bromide complex, MAIN GR MET, 22(8), 1999, pp. 515-518
Reaction of equimolar quantities of gallium(lll) bromide and 1,4,7-trimethy
l-1,4,7-triazacyclononane (Me-3[9]aneN(3)) in acetonitrile gives the neutra
l adduct [GaBr3(Me-3[9]aneN(3))]. A crystal structure determination (X-ray
diffraction) confirms a half-sandwich topology in which the six cc-ordinate
metal centre adopts the expected fac-octahedral geometry, following eta(3)
N-donor co-ordination of the azamacrocycle.
